| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What are the two main types of plant reproduction? | The two main types of plant reproduction are sexual reproduction and asexual (vegetative) reproduction. | Think about how plants can reproduce with or without fertilization. |
| 2 | What is pollination in plants? | Pollination is the transfer of pollen from the male anther to the female stigma, enabling fertilization in flowering plants. | Consider the role of pollinators like bees and wind. |
| 3 | Name three agents that can facilitate pollination. | Agents of pollination include insects (bees, butterflies), wind, and animals (birds, bats). | Think about different ways pollen reaches the ovule. |
| 4 | What structures develop from fertilized ovules in flowering plants? | Fertilized ovules develop into seeds, which contain the embryo of the new plant. | Remember what a seed is in plant development. |
| 5 | What is seed dispersal, and why is it important? | Seed dispersal is the movement of seeds away from the parent plant, which helps reduce competition and allows colonization of new areas. | Think about how seeds spread in nature. |
| 6 | Name three methods of seed dispersal in plants. | Methods include wind dispersal (e.g., dandelions), animal dispersal (e.g., berries eaten and excreted), and water dispersal (e.g., coconut). | Consider how different seeds travel long distances. |
| 7 | What is vegetative propagation in plants? | Vegetative propagation is a form of asexual reproduction where new plants grow from parts of the parent plant, such as stems, roots, or leaves. | Think about cloning plants without seeds. |
| 8 | Give an example of a plant that reproduces via vegetative propagation. | Strawberries reproduce via runners, and potatoes produce new plants from tubers. | Recall common garden plants or fruits. |
| 9 | How does grafting facilitate plant reproduction? | Grafting involves joining a stem (scion) of one plant to the root system (rootstock) of another, allowing reproduction of desirable plant varieties. | Think of fruit tree propagation. |
| 10 | What are the advantages of asexual reproduction in plants? | Advantages include rapid colonization, production of genetically identical offspring, and survival in stable environments. | Compare to sexual reproduction's genetic diversity. |
| 11 | What are the disadvantages of asexual reproduction in plants? | Disadvantages include lack of genetic diversity, making populations more susceptible to diseases and environmental changes. | Think about risks of uniformity. |
| 12 | Which part of a flower develops into a seed after fertilization? | The ovule develops into a seed after fertilization. | Remember the role of the ovule in reproduction. |
| 13 | What is the function of the pollen grain in plant reproduction? | The pollen grain contains the male gametes (sperm cells) necessary for fertilization of the ovule. | Think about what carries the male genetic material. |
| 14 | Describe double fertilization in flowering plants. | Double fertilization involves one sperm fertilizing the egg to form the zygote, and another sperm fusing with two polar nuclei to form the triploid endosperm, which nourishes the developing embryo. | Unique feature of angiosperms. |
| 15 | What is the role of the flower's stigma and style in reproduction? | The stigma receives pollen, and the style provides a passage for pollen tubes to grow toward the ovules for fertilization. | Focus on pollen reception and transport. |
| 16 | How do wind-pollinated plants differ from insect-pollinated plants? | Wind-pollinated plants produce large quantities of lightweight, smooth pollen and often lack bright petals, whereas insect-pollinated plants have colorful, scented flowers to attract pollinators. | Think about adaptations for different pollination agents. |
| 17 | What is apomixis in plants? | Apomixis is a form of asexual reproduction where seeds are produced without fertilization, resulting in offspring genetically identical to the parent. | Cloning via seed production. |
| 18 | What is vegetative propagation through tubers? Provide an example. | Vegetative propagation through tubers involves new plants growing from underground storage organs; potatoes are a common example. | Remember that tubers are modified stems or roots. |
| 19 | Why is seed dormancy important for some plants? | Seed dormancy prevents germination until environmental conditions are favorable, ensuring seed survival and successful growth. | Think about timing of germination. |
| 20 | What role do humans play in plant reproductive strategies? | Humans facilitate reproduction through techniques like grafting, seed selection, and cultivating plants for agriculture and horticulture. | Consider how humans influence plant propagation. |
